Acyclic nucleosides bearing a furanyl scaffold

Area of Science:

• Medicinal Chemistry
• Organic Synthesis
• Virology

Background:

• Acyclic nucleosides are crucial in antiviral drug development.
• Developing novel nucleoside analogues is essential for combating viral infections like HIV.

Purpose of the Study:

• To synthesize novel acyclic nucleosides featuring a furanyl scaffold.
• To evaluate the biological activity of these novel compounds against HIV and related enzymes.

Main Methods:

• Construction of the base moiety onto a dihydrofuranyl intermediate.
• Synthesis of adenine (A) and cytosine (C) analogues.
• Assay of substrate activity toward deoxycytidine kinase.
• Evaluation of anti-HIV activity.

Main Results:

• Successful synthesis of acyclic nucleosides with a furanyl scaffold.
• Adenine and cytosine analogues showed some substrate activity for deoxycytidine kinase.
• The synthesized compounds lacked significant anti-HIV activity.

Conclusions:

• The developed synthetic strategy allows for the creation of furanyl-based acyclic nucleosides.
• While showing some enzyme interaction, these specific analogues are not potent anti-HIV agents.
• Further structural modifications may be necessary to achieve significant antiviral efficacy.
